SCREEN FOR GUN-SIGHTS.

SPECIFICATION forming part of Letters Patent No. 621,066, dated March 14, 1899.

Application filed December 23, 1897. Serial No. 663,174. (No model.)

To all whom it may concern:

Be it known that I, THOMAS GILBERT-RUS- SELL, a subject of the Queen of Great Britain, residing at Neasden, London, in the county of Middlesex, England, have invented certain new and useful Improvements in Sighting Devices for Firearms, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to sighting devices for firearms and it has special relation to improvements in holders for fixing and adjustmoved so as not to form an obstruction when out of use; and the object of my present invention is to provide a simple and improved holder which will effectively obviate the above-named objections.

The invention is fully disclosedin the following specification, of which the accompanying drawings form a part, in which Figure l is a side elevation of a portion of a rifle of the Martini-Henry type, showing my improved holder for applying the screen or disk thereto, the said screen being shown in its raised position for use when firing. Fig. 2 is a plan view of the construction shown in Fig. 1. Figs. 3 and 4 are sectional views taken, respectively, on the lines 3 3 and 4 4, Fig. 2. Fig. 5 is a detail plan view of the holder, showing the screen turned down out of use. Fig. -6 is a side elevation of a portion of a Mannlicher rifle, showing the construction and arrangement of my improved holder which I employ for applying the screento Fig. 7 is a plan view of the form of construction shown in Fig. 6. Fig. 8 is a transverse sectional view taken on the line 8 8, Fig. 7. Fig. 9 is a side elevation showing the construction of my improved holder when applied to a rifle of the Winchester type. Fig. 10 is a sectional view taken on the line 10 10, Fig. 9. Fig. 11 is a side elevation showing the form of holder I em ploy in the application of my invention to a double-barrel sporting rifle or gun. Fig. 12 is-a sectional view taken on the line 12 12, Fig. 11. Fig. 13 is a sectional View taken on the line 13 13, Fig. 12. Fig. 14 is a side elevation of a form of construction similar to that shown in Fig. 11, but the holder being hinged so that it can be turned down out of use. Fig. 15 is a sectional view taken on the line 15 15, Fig. 14.. Figs. 16 and 17 are detail elevations, at right angles, of the holder shown in Figs. 14 and 15. Figs. 18 and 19 are elevations at right angles, showing a further modification in the form of the holder illustrated in Figs. 14 to 17, inclusive.

In the drawings forming part of this specification the separate parts of my improve ment are designated by the same letters of reference in each of the views, and in said drawings, a designates the screen,whi ch may be formed of leather, india-rubber, or other flexible or suitable material.

My improved holder embodies an arm 1), divided or forked, as shown at c, to receive the screen a, the screen being held in the arm by a set-screw d, which also serves for clamp ing the screen in any position to which it may be adjusted.

In a rifle of the Martini-Henry type,asil1ustrated in Figs. 1 to 3, inclusive, the arm 19 is provided with a pivot-pin e, carried in bearings f f on a base-plate g. This base-plate for a rifle of the Martini-Henry type is of such a shape that it can be applied to the upper surface of the barrel, as clearly shown in Fig. 3. A spring 72. is carried by the base-plate g, and flats t 't' are formed upon, the pivot-pin e, (see Fig. 4,) against which flats one end of the spring bears to hold the arm I) in its upward and downward positions, the other end of the spring being attached to the baseplate 9.

In the application of my improved holder to a rifle of the Mannlicher type, as shown in Figs. 6 to 8, inclusive, the base-plate g is constructed so that it can be applied to the side of the frame. (See Fig. 8.) This form or construction of the holder preferably has a narrow kerf or slit cl at its base, which permits the set-screw to draw or clamp the fork together, and thus firmly hold the leather or flexible screen in either position. The baseplate is provided with a shoulder g, below which extends a side plate or tang 9 adapted to be secured to the side of the frame by means of a fastening-screw g or in any other suitable manner. The spring h is arched and is preferably provided with studs 7t at its ends, which are received by recesses or openings g in the shoulder of the base-plate. The cylindrical base portion of the forked arm bears upon the arched spring and serves to retain the latter in place, and the flats 'Z i are formed upon this loweror base portion of the fork and operate with relation to the top of the arched spring.

By the constructions and arrangement as above described, adapted for application to either a rifle of the Martini-Henry type, as shown in Figs. 1 to 3, inclusive, or arifle of the Mannlicher type, as shown in Figs. 6 to S, inclusive, the arm I), and with it the screw (Z, can be turned down and out of use over the barrel, as indicated by the dotted lines in Figs. 1 to 6 and in full lines in Fig. 5, the screen being first turned upon the screw cZ into the position shown by the dotted lines in Fig. 3.

The construction of parts and the general form as above described for Mannlicher rifles are also adapted for convenient and effective application upon other modern repeating rifles of various types and on military rifles as now generally used.

In rifles which have a flat-sided frame, such as the Vinchester type, as illustrated in Fig.

- 9, I dispense with the base-plate g and pivot the arm 1) upon a pin 6, secured to the side of the frame, the arm being of a general shape or contour, as shown, adapted to enable the screen when turned down out of use to lie or rest upon the top of the barrel, as in the constructions before described. The arm I) for this type of rifles is extended below the pin e, as at b, the spring 7L being arranged to bear against the edge of the said part b, which latter is provided with the flats i Z, against which the said spring bears when the arm I) is in its raised or lowered positions, the arm Z) being thus maintained in such positions.

In its application to a double-barrel gun, as shown in Figs. 11 and 12, the arm Z) is inclined outwardly and upwardly and is either straight, as shown by the dotted lines in Fig. 12, or curved, as shown by the full lines in the said figure, whereby it can be fixed in a hole or recess Z in the solid part of the breech and serve to carry the screen a in the proper position for use. The screen is fixed in the arm I) by the screw (Z. To provide for a tight retention of the arm bin the hole or recess Z, the arm is preferably divided at its lower end, the two parts being slightly forced apart, so as to act as a spring. The arm is also prevented from twisting or turning when inserted in the holeZ by means of an end tooth m, which enters a corresponding notch. In this construction of the holder the arm Z) is withdrawn from the hole or recess Z when the screen is not required for use.

In Figs. 14 and 15 I have shown a construction in which the arm I) is formed of two parts hinged together, the lower part b being provided with a screw-thread, so that it can be fixed in the hole Z, which is correspondingly screw-threaded. The lower end of the upper part of the arm I) may be bifurcated, so that it'will embrace the head of the part b at the hinged joint. To provide for the rigid retention of the arm I), and with it the screen a, in proper position when turned up for use, I prefer to provide a pin Z, having a rounded end which projects slightly beyond one face of the head of the part b and enters a hole Z in one side of the fork. The upper part of the arm I) may be provided with a kerf or slot, as at Z2 which renders the fork somewhat elastic, so that when the fork is turned down, as shown in Fig. 14:, the sides of the fork will be sprung apart as the pin Z is disengaged from the hole Z hen the screen is again turned up into position for use, the pin Z will again engage the hole Z under the spring action of the fork and hold the arm Z), and with it the screen a, rigid.

In some cases I dispense with the hinge in the form of holder shown in Figs. 14 and 15, the device being simply constructed and arranged so that the arm Z) can be unscrewed and withdrawn from the hole Z when not required for use, this modified construction being shown in Figs. 18 and 19. v

The use of the disks or screens for which my improved holder is especially adapted has heretofore been inconvenient and subject to many disadvantages by reason of the essential positions which such disks or screens must take when in use, and my present holder is designed to obviate these disadvantages by providing a convenient and effective method of attachment for the application and use of the disk or screen under various circumstances.

I-Iaving fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a forked arm adapted for attachment to a firearm of a sightscreen situated between the sides of the fork, and means for clamping the sides of said fork upon said sight-screen.

2. The combination with a forked arm mounted in pivotal connection with a fire arm and adapted to fold or turn with relation to the same upon its pivot, of a sight-screen situated between the sides of said fork, and means for clamping the sides of the fork upon the sight-screen.
